M&L for preparation of old black top surface by brushing with wire brushes for removing caked mud etc sweeping with brooms and finally fanning the cleaned surface with air blower to remove loose dirt etc. complete and apply cold polymer modified emulsion (PME) by using mechanical spraying of total cold liquid PME 1 ltr per sqm (undiluted) for two coats with mineral filler as recommended by manufacturer of PME (after diluting with water), each coat diluted in the ratio 1:1 (PME: WATER) and ensure uniform finish of applied flight strips complete all as per manufactcurer instructions all as specified and directed by Engr-in-Charge

Removel of conflict paint , markings on Apron & runway surface using water blasting cum vacuuming system with suitable operating pressure so that total paint removed from runway both (rigid & flexible) surfaces without damaging the existing surface using suitable machinary all as specified and as directed by Engr-in-Charge.

(e) Pre Execution of Trial patch : Prior to full scale deployment of the machinery on the main runway, a trial patch shall be executed . This trial will test the operational efficiency of the equipment, verify that no structural damage occures to the pavement and allow for fine tuning/ modulation of operating pressure based on actual site observations. (f)In any emergency condition the machine should exit from runway in less than two minutes without leaving any FOD. (g)Majority of the works to be carried out during night time, bidder should arrange proper illumination for execution of the work
